To all whom tt may concern.'

Be it known thatvI, JOHN S. BAYER, e citizen of the United States, residing et Narren in the county of Terran and State oflenn Sylvania, have invented certain new sind useful Improvements in Culverts, of which tlrgnollotv'ing is e specification.

ticularly to improvements in fastening means for securing thel sections together' or when the pipesnre Inadeoi heli sections, for securing those half sections together; and among the objects accomplished by my involition, it may be mentioned that no speciall machinery is required in the manufacture of the culvert, which is quite" a desidereturn; another object is to i provide a.' culvert in which the ends ofthe sections when made in a, single piece, or the` edges .when in heli sec- .i tions, are reinforced-fwhereby to give them greater strength;"enother object is to pro;

Ivide eculvert which may oe put together as it is put in piece-setlist the entire roadway does nothave tov beclosed as the culvert s being put A A further object is 'to provide a culvert Whichvmay be made in half sections if desired, so that the sections may he nested in Atransportsticn whereby the cost of handling and freight is decreased, and when thus made in sections, the sections are precisely alike, so that they may he easily and quickly' Jiitted to ether. c y,

iththe foregoing objects' in view, my presentinvention consists in certeinnovel features of construction and combinations of parte which will he hereinafter described and pointed out in the claims.

In the accompanying drawings Figure l is a perspective view of two heli sections seperated. `Fig. 2 is a. plan view showing two mein sections secured together. Fig. 3 is a detail in transverse section through thc fastener. Fig. 4 is o fragmentary view inv -detail showing the application oi' the iniprovenient to the ends of sections made in a In te preferred forni, the construction i1 shown in Fig. l, A and B are the two sections. i These are mede of corrugated sheet* metal precisely alike so that they ere interchange able end can he fitted together in any mnner. 'On one edge of eech section, a plete* fis riveted 'or otherwise'secured, the outer`edge having en oiiset flange Z whereby n socket is formed to receive the corresponding edge oi the other half section. This plctenot only forms e simple and an .effectual joint ket the edge, lout also reinforces the halt sections et opposite edges longitudinal Vof the culvert sections, thus giving additional strength.. Un the inneredges of this plete, lips. 5, 5, may he formed to receive the hooked ends d, 6, ofthe oolts 7, 7, and these b'olts extend through the holes 8, 8,in the lugs. 9, 9, se'- cured on the other sections, after which the nuts 10, 10, are screwed tight, end the heli sections are held together.

In, forming :t culvert and assembling the Y sections, the ends ofethe half sections ere separated to receive the adjacent ends oi the next section, after which they are clamped securely together, thereby making a rigid and eiiectual oint which Will'notpull apart. In the construction shown in Fig. 4, this seine idea is applied to the end of the culvert sections, the sections in this instance being made in e single piece, instead of two heli sections.

The greet advantage of this invention is, and especially When the culvert is made in half sections as indicated, that these half sections muy he nested, end thus 'the cost ci hendiin end freight is reduced to a niinimuni.' there are 'many other advantages,

.some of which I have alreedy specified .in the statement oi" the object of the invention, hut it is perfectly ohviousthet the assembling of the verts is simple and effectual and is of such cnsrncter thet it may he accomplished Where the Work oi putting in 'e culvert is heing carried on, which is n very materiel edvantege over building the l.culvert at 'the iactory, which is exactly what is required. for tue culvert to he built in accordance with the present practice. The fact that` each half section is en. interchangeable part is a very decided advantage es it Inekes the section light, easy to manufacture, Without requiring special machinery, and ust as easy to put ltogether, and it makes it very convenient and simple to esseinhle or handle the'culvert, and to lock. them together so that they are inseparable.

Another advantage of this form of culverlt is that the punching ,and riveting ma be all done by'rnachinery vhich is unpossi lein a construction Where he rivets are located a long distance from the edge as all of tlxesetvetA holes'and rivets are either ratfthe end edge of a section',v ade all in one piece, or at the'side edges of a'half section, Where va length made in hal sections. y

More' or less slight changes might be resorted to in the form and arrangement of the several parts described Without departing from the s irit and sco e of my invention, and hence do not W'isli 'to limit myself to the exact construction herein set forth, but

Having fully described my invention, What I clairnas new'and desire to secureby Letters Patent, is* -f/ 1. A culvert, each section of which is made edges, and means for tightening' said bolts i I whereby to drew the sections securely together. l

, 3. 'A culvert, the lengths of which are cornposed of half sections made of sheet metal and havin a flanged plate secured to one edge Where y to form a socket to receive an edge ofthe other half section, and adjustable.

fas'.,ening means for securing the half sections together. I

4. A culvert, the lengths 0f which are cornpos'ed of half sections made of. corrugated sheet metal and having a flanged 'plate se cured to one ed ewhereby to form a socket to receive an e ge of the other half section,

and adjustable fastening `means for securing I the half sections together. 7 A 5. A culvert composed of'corrugated sheet metal half sections, all of which are alike,l a

flanged plate secured'toone side edge/f'each4 v' half section, hooked bolts adapted tobe con-- nected with the acl-'acent edgesgof'vsaid half sections, and nuts t ereon for drawingV them up to secure the half sections together.

In testimony whereof I aixrn'y signature in presence of two witnesses.
